Nose hair cutter

Abstract

A main body of an inner blade is inserted into an inner blade insertion hole of an inner blade frame such that the main body can extend and retreat, a tip end cutting edge is pushed by a spring such that it comes into contact with an inner peripheral surface of a slit outer blade, the main body of the inner blade projecting outward from the inner blade insertion hole is bent rearward in a rotational direction, and the cutting edge of the inner blade is located rearward of the main body in the inner blade insertion hole in the rotational direction. With this configuration, the cutting edge does not fall forward in the rotational direction, and no gap is generated between the cutting edge and the inner peripheral surface of the slit outer blade.

1. A nose hair cutter comprising:
 a slit outer blade having an inner peripheral surface; 
 a rotatable inner blade comprising a main body and a cutting edge, 
 wherein said cutting edge of said inner blade is elastically biased such that it contacts said inner peripheral surface of said slit outer blade; and 
 an inner blade frame having an inner blade insertion hole and a joint insertion hole, 
 wherein said joint insertion hole extends through said inner blade insertion hole to enable an electric motor to rotate said inner blade, 
 wherein said main body of said inner blade is received by said inner blade insertion hole and extends from said inner blade insertion hole, and 
 wherein said main body projects outwardly from said inner blade insertion hole such that said cutting edge is located rearward of said main body, in a rotational direction. 
 
     
     
       2. The nose hair cutter of  claim 1 , wherein said cutting edge is rearwardly positioned with respect to a portion of said main body located at said inner blade insertion hole. 
     
     
       3. The nose hair cutter according to  claim 1 , further comprising:
 a detent projecting from said main body of said inner blade; 
 a retaining recess positioned internally of said inner blade frame, 
 wherein said retaining recess is configured to retain said detent of said main body. 
 
     
     
       4. The nose hair cutter of  claim 1 , wherein the main body further comprises:
 a first arm extending substantially radially from said inner blade insertion hole, and 
 a second arm extending rearwardly from said first arm in the rotational direction, 
 wherein a bend defines a connection between said first and second arms and said second arm includes said cutting edge. 
 
     
     
       5. The nose hair cutter of  claim 1 , wherein the main body further comprises:
 a first arm extending substantially radially from said inner blade insertion hole; 
 a second arm extending rearwardly from said first arm in the rotational direction; 
 a third arm extending forwardly from said second arm in the rotational direction, 
 wherein a first bend defines a connection between said first and second arms, a second bend defines a connection between said second and third arms, and said third arm includes said cutting edge. 
 
     
     
       6. A nose hair cutter comprising:
 a slit outer blade having an inner peripheral surface; 
 a rotatable inner blade comprising a main body and a cutting edge, 
 wherein said cutting edge of said inner blade is elastically biased such that it contacts said inner peripheral surface of said slit outer blade; and 
 an inner blade frame having an inner blade insertion hole, and a joint insertion hole extending through said inner blade insertion hole of said inner blade frame to enable an electric motor to rotate said inner blade, 
 wherein said main body of said inner blade is received by said inner blade insertion hole and extends from said inner blade insertion hole, 
 wherein said main body extends substantially radially from said inner blade insertion hole, and 
 wherein said main body projects outwardly from said inner blade insertion hole such that said cutting edge is located rearward of said main body, in a rotational direction. 
 
     
     
       7. A nose hair cutter comprising:
 a slit outer blade having an inner peripheral surface; 
 a rotatable inner blade comprising a main body having a detent, and a cutting edge, 
 wherein said cutting edge of said inner blade is elastically biased such that it contacts said inner peripheral surface of said slit outer blade; and 
 an inner blade frame having an inner blade insertion hole and a joint insertion hole, 
 wherein said inner blade insertion hole comprises a retaining recess configured to retain said detent of said main body and said joint insertion hole extends through said inner blade insertion hole to enable an electric motor to rotate said inner blade, 
 wherein said main body of said inner blade is received by said inner blade insertion hole and extends from said inner blade insertion hole, and 
 wherein said main body projects outwardly from said inner blade insertion hole such that said cutting edge is located rearward of said main body, in a rotational direction.
